This concept has its baseon the principle of effective use of military power.This principle requires close integration of theefforts of the separate military services. Unity ofeffort among the services at the national levelresults from a joint effort. The Secretaries of theArmy, Navy, and Air Force, the JCS, and thevarious military departments work together in thisjoint effort.Under the National Security Act, each militarydepartment and service must coordinate withthe others. Each is responsible for organiz-ing, training, equipping, and providing forcesto fulfill certain specific combat functionsand for controlling and supporting theseforces.The full use and exploration of the weapons,techniques, and capabilities of each departmentand service are essential in attaining our nationalsecurity goals.UNIFIED COMMANDSA unified command is a command, with abroad continuing mission, composed of signifi-cant components of two or more services undera single commander. When either or both of thefollowing criteria apply to a situation, it requiresa unified command:1.
